JOHN P. NESSLE, OF NE\VARK, NEW JERSEY.

WHISTLE-HARP.

SPECIFICATION forming part of Letters Patent No. 471,015, dated March15, 1892.

Application filed September 26, 1891. Serial No. 406,915. (No model.)

T all whom, it may concern,.-

Be it known that I, JOHN P. NESSLE, of Newark, in the county of Essenand State of New Jersey, have invented a new and Improved MusicalInstrument, which I have named a Whistle-Harp,77 of which the followingis a full, clear, and exact description.

My invention relates to improvements in musical instruments; and theobject of my invention is to produce a cheap and simple device which maybe played by blowing into it and which with a little practice may bemade to play any desired tune.

To this end myinvention consists in certain features of construction andcombinations of parts, which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forminga part ofthis specification, in which similar iigures of reference indicatecorresponding parts in all the views.

Figure 1 is a longitudinal section of the whistle-harp on the line 1 1in Fig. 2. Fig. 2 is a cross-section on the line 2 2 in Fig. 1. Fig. 3is a longitudinal section on the line 3 3 in Fig. 1. Fig. 4 is alongitudinal section of a modified form of whistleharp on the line 4 4in Fig. 5, and Fig. o is a cross-section on the line 5 5 in Fig. 4.

The instrument is provided with a hollow body 10, which is preferably ofa rectangular shape, butwhich may be madeof anyshape, and the body ispreferably made of metal, so that it will be resonant. The body has anopening 11 at one end, which is applied to the mouth when the instrumentis to be played, and the body has also longitudinal slots 12 on oppositesides to permit the escape of air. One end of the body is closed bya cap13, so that when the body is blown into the air must escape from thesides. The body is provided on two sides with longitudinal grooves 15,the grooves being made in the inner wall of the body, and the groovesare produced adjacent tothe corners of the body and are adapted toreceive the plates 14, which tit closely in the grooves and which areprovided with central slots or openings passing outward through theopenings 16 and 12 will cause the tongues 17 to vibrate, so as to emitmusical sounds, and the tone is varied so as to produce a tune byworking the tongue in the same manner as if whistling without the use ofan instrument. It is essential that the body have an inside lengthexactly corresponding with the length of the plates 16, as otherwise notune can be .produced.

In Figs. 4 and 5 I have shown a moditled form of the device in which asingle plate is used, and in this form the body 10a is preferably madeof cylindrical form; but it may be ot any desired shape. The grooves 15are produced centrally in the body, so as to receive the plate 14, andone end of the plate is bent at a right angle, as shown at 14a in Fig.4, so as to close one portion of the body. This plate divides the bodyinto two compartments 18 and 19, the compartment 18 having an opening11"" at one end, into which the operator blows, and the compartment 19having its top end adjacent to the opening 1l closed, as shown at 19u.

This device is operated in the manner already described, and, as in theother case, the length of the body and of the resonant plate mustexactly correspond.

Having thus fullydescribed my invention, I claim as new and desire tosecure by Letters Patent- 1. A whistle -harp comprising a tubular bodyhaving opposite parallel longitudinal grooves 15 in its inner side,inlet and outlet openings, and a slotted slide 14 of the same length asthe inside length of the body mounted at its longitudinal edges in saidsaid grooves and hav-ing longitudinal slots provided with reeds ortongues, substantially 1` grooves andA having a reed or tongue,substantially as set forth.

2. A Whistle-harp comprising a tubular as set forth.

body having an opening 1l in one end, a cap i 5 13 closing its oppositeend, longitudinal slots JOHN P' NESSLB" 12 12 through its oppositesides, two pairs of Witnesses:

internal longitudinal grooves 15 in the other Sp1-I. PENNINGTON, Jr.,

two sides, and a pair of slides 14, mounted in J AMES VAN HORN.
